PROCESSING APPARATUS AND STACKER DEVICE

A processing apparatus comprises: a conveyance part for conveying a sheet; a processing part including a processing member that is installed in a manner of being movable in an intersecting direction of intersecting with a conveyance direction of the conveyance part and that performs predetermined processing at a predetermined position of the sheet under conveyance; a stacker part for accumulating processing articles obtained by the processing of the processing part; and a control part for controlling the stacker part such as to sort a predetermined amount of precedently ejected ones of the processing articles from the subsequent ones of the processing articles among the processing articles ejected to the stacker part by the conveyance part.

Printing and perforating machine
20240399606 · 2024-12-05 ·

Printing and perforating machine comprising a perforating mechanism (1) and a printing mechanism (30), the perforating mechanism (1) comprising a perforating element (2, 7) provided with piercing elements (5); and a support element (4, 8) that defines with the perforating element (2, 7) a space for the passage of a sheet material (3), forming holes on the sheet material (3) when it passes through this space. With this machine, the perforation of the sheet material is carried out during the printing process thereof, preferably a digital printing, in a synchronized way, eliminating time and handling for loading and unloading the roll of sheet material in a conventional sheet material perforating machine.

Devices for post-processing web- or sheet-type stock, production line, and method for producing a printed product

A device for further processing web- or sheet-type stock comprises a further-processing section, in which stock that is supplied on the input side can be processed into printed products. The further-processing section comprises, in the guide path of a processing line through which the stock has run, at least one first combining device relative to the stock path, which can combine one- or multi-layer stock sections to a bundle; a second combining device which can combine the bundles formed by the first combining device to a bundle stack downstream of the first combining device; and a transverse folding device which is arranged functionally downstream of the second combining device and which transversely forms the bundles or bundle stacks relative to the conveying device on the input side when they exit the second combining device. A device for joining several layers is placed in the guide path, such that it can join several or all of the stock sections combined in the first combining device into a bundle, before they are received by the second combining device and is associated with, are arranged downstream of the first combining device. During production of the products, a combined bundle is stapled before it is combined with one or more other bundles and is then transversely folded. In addition, a longitudinal cutting device is provided in the guide path downstream of the transverse folding device.

Post-processing device and image forming system

A post-processing device includes a sheet transporting section that transports one or more sheets, a cutting section that cuts the sheet along a transporting direction of the sheet being transported by the sheet transporting section and a paper piece transporting section that transports a paper piece cut by the cutting section, and a transporting speed of the paper piece transporting section is set lower than a transporting speed of the sheet transporting section.
